Thanks, but what I'm talking about are the 6Gb or thereabouts things that Specaircrew has mentioned. The Creative Labs Nomad is the first one to be on general release in the UK but the ohters are avilable on line through amazon and some specialist outlets.
I was put off the Nomad because of the relatively poor battery life and because you can't transfer data back to your PC.
Some of the others, you can use as a portable HD as well as mp3 players and would be handy to use the spare space as a PC backup for important files etc. You can get upto 20Gb HD now too.
